Dunno if you've realized this, but the flamethrower is screwy unless fired perfectly straight a 180 degree angle. Like, fire particles will come out at random angles if I tilt it up or down.

Wouldn't weigh you down anymore than carrying the extra ammo in the first place.
But oh wait, the ammo is gone, so it'd be LIGHTER.

It'd be lighter, but still weigh you down alot.
Early (If you were a shinobi), and Later on (If you were a Shogun).

I'd rather be weighed down than pollute the environment with my cast-aside magazines.

id rather they vaporised. kidding.. it did look pretty cool though.

You'd think they would have the technology to have biodegradable magazines by now.

Hmm, chaff grenade effects, when it decays... I want it now!

Uhm... looks fine to me.

... You realize that they were carrying the magazines on them in the first place. Keeping the magazines is also economically feasible. There isn't a real downside to it, because you arrived at your fight with them already, I mean unless you came over prepared, weighed down with ammo... Even then, as said before they're empty, therefor they're incredibly lighters.

You don't seem to understand.
You've always been carrying the extra weight, because the ammo has to come from somewhere.
So not dropping the spent magazines isn't weighing you down, it's just refusing to remove weight.

stubborn little ninjas..

I don't care if whether or not they're carrying their magazines. I liked it when they dissolved! It was a pretty and interesting special effect.

Even though I make an impeccable point that only compliments my good looks and intellects. I must agree.

Oh NeoSeeker, why are you so handsome?

I didn't think everyone cared so much about the disintegrating magazines. But, isn't there some CC concept of regenerating magazines? Like, we could just assume that the actors are switching off between a few magazines, using one while the others regenerate their ammo.

It's kinda weird, but I swear I saw the concept somewhere. It wouldn't really explain why the base actors drop their mags, though.

But really, regardless of dropping mags or keeping mags, it still doesn't answer the question where all these magazines come from in the first place. Every actor seems to come with an infinite supply, for whatever gun they happen to have, whether they came with it or they just randomly picked it up in the battlefield.
